my subaru had a studder at 4k rpm for literally 3 years or so, finally it threw a maf related code.
I cleaned it gently with the crc stuff and it didnt really help.
Since my next step was to buy a new sensor, I got a bit more midevil with the stuff and sprayed tons of it directly into the sensor. I used basically the whole can on the sensor.
Car ran like a champ right away. I had gotten so use to the stumble at 4 k-rpm that it surprised me occasionally when it was gone
